The main plaintiff in the Hawaii case blocking President Trump’s revised temporary travel ban is an imam with ties to the Muslim Brotherhood.

The irony is hard to miss: Trump has talked about declaring the Muslim Brotherhood a terrorist organization, and now it is a Brotherhood-backed imam who is playing a key role in blocking his executive order on immigration.

Imam Ismail Elshikh, 39, leads the largest mosque in Hawaii and claims he is suffering “irreparable harm” from the president’s executive order, which places a 90-day ban on travel to the U.S. from six countries.

One of those six countries is Syria. Elshikh’s mother in law is Syrian and would not be able to visit her family in Hawaii for 90 days if Trump’s ban were allowed to go into effect.

Imam Ismail Elshikh, a native of Egypt, leads a Muslim Brotherhood-tied mosque in Honolulu, Hawaii, and claims he is suffering ‘irreparable harm’ by President Trump’s temporary travel ban.

“Plaintiffs allege that the Executive Order subjects portions of the State’s population, including Dr. Elshikh and his family, to discrimination in violation of both the Constitution and the INA, denying them their right, among other things, to associate with family members overseas on the basis of their religion and national origin. The State purports that the Executive Order has injured its institutions, economy, and sovereign interest in maintaining the separation between church and state.”
